2C-T-21 Dosage Guide

## Assessing a 2C-T-21 Emergency There is no published clinical data on 2C-T-21 overdose or adverse events. Emergency response must be guided by protocols for thio-substituted 2C compounds generally, with additional vigilance for signs that could indicate fluoroacetate-related toxicity. **Signs of serotonin syndrome (treat as medical emergency):** - Body temperature above 39°C (102°F) and rising - Sustained heart rate above 150 bpm - Muscle rigidity, clonus (involuntary rhythmic jerking), sustained tremor - Agitation progressing to confusion or delirium - Seizure of any duration - Profuse sweating with inability to thermoregulate **Signs that may indicate broader metabolic toxicity:** - Chest pain or irregular heartbeat (cardiac tissue is vulnerable to both serotonin toxicity and theoretical fluoroacetate-mediated energy failure) - Persistent, severe fatigue disproportionate to the psychedelic experience - Oliguria (reduced urine output) -- potential indicator of renal stress - Prolonged confusion beyond expected psychedelic effects duration ## Emergency Response 1. **Call emergency services.** State: "Adverse reaction to a serotonergic research chemical with potential serotonin syndrome." Provide the substance name (spell it: "2C-T-21, a fluorinated thio-phenethylamine"), dose, time of ingestion, and any other substances taken. Emergency physicians may not be familiar with this compound -- the critical information is that it is serotonergic with MAO-interacting properties 2. **Begin cooling immediately.** Hyperthermia is the proximate killer in serotonin syndrome. Remove excess clothing. Apply ice packs to armpits, groin, and neck. Mist skin with water and fan aggressively. Evaporative cooling is the most effective field technique 3. **Benzodiazepines for agitation and seizures.** Diazepam or lorazepam if available. Do not use antipsychotics -- they can worsen serotonergic crises and some (haloperidol) lower the seizure threshold 4. **Monitor continuously.** Airway, breathing, pulse. If consciousness is lost, recovery position. Be prepared for CPR 5. **Record timeline.** Time of ingestion, dose, route, other substances, sequence of symptom development. This information is critical for hospital management ## Managing Psychological Distress If the person is physically stable but experiencing intense anxiety, fear, or perceptual disturbance: - Move to a calm, quiet space with minimal stimulation - Speak slowly and clearly. Use their name. Maintain gentle eye contact - Anchor them with simple physical grounding: hands on a cool surface, feet on the floor, cold water on wrists - Remind them that the effects are caused by a substance and will end. "This is a drug effect. It is temporary. You are safe." - Do not leave them alone for any duration - If distress does not improve within 30 minutes, or if reality testing is impaired (they cannot distinguish hallucinations from reality, or they express intent to harm themselves), seek emergency medical attention Good Samaritan protections apply. Never delay calling for help because of legal concerns.
